4G Complexity is Daunting

New Technology Equals Churn

• New Devices / Standards - Daily

• High Feature Velocity

• Rapid bug fix releases

This makes an already challenging problem quite frustrating

Test Area:– Formfactors / Design

– FPGA

– Processors

– Display

– Keypad

– Touchscreen

– Camera

– Microphone

– Battery and Charger

– Data Cables (Video, USB)

– Headset

– Headset Bluetooth

– Lamp

– Storage

– Data Card (removable)

• Radio Interface (RF)

physics & controlEn-/Decoding

Throughput

• IR

• Bluetooth

• WiFi

• FM Radio

• GPS

• Additional keys for e.g.

• Loudness

• Camera

• Switch on/off

• Sensors (if applicable)

Hardware and Interfaces Software and Interfaces• Platform Capabilities

– Operating System (S60, Windows Mobile etc)

– Platform SDK

• Security• Audio

• Quality

• Codecs

• Voice recording

• Speech recognition (Voice dialling)

• Video• Quality

• Codecs

• Video recording

• Content and File Management

• DRM

• File Manager

• Data transfer via BT, IR, USB

• Graphics

• Applications without network interaction– Music

– Gaming

– Java

– Phonebook

– Calendar

– Clock / Alarm / Worldclock

– Editor

– Document viewer

– Caculator

– Currency converter

– GPS

– Radio FM

• Applications with network interaction– Mobile TV

– SMS

– MMS

– Download, upload files, pictures, videos

– Interactive gaming

– Calendar synchronisation

– Email

– Push to talk

– Web browsing

– WAP

– Call Register (in / out / missed)

– VoIP

– IPv6

• Application Interactions – With and without network interaction)

• Application running from Memory Card• Flight Mode

• Concurrency e.g.– Mobile TV and incoming call– Write SMS and incoming call– Receive SMS/MMS during Call– Receive call while any of the applications is running– Video Conference and MMS– Streaming service and incoming/outgoing call– Upload data and and incoming/outgoing call– ...

Layer 2/3 Protocol Testing (Network Signaling) GSM/GPRS/EDGE UMTS/HSPA LTE (example follows)

• Module Testing

• HW/SW Integration• System Integration

2G/3G Mobility IntraRAT-Handover InterRAT-Handover

Protocol Conformance Testing ( ->GCF)

• Services e.g.– Supported Bearers

• SIP / IMS applications (as VoIP !!)

• MBMS (as Mobile TV)

• Different Qos/QCI (=QoS class Identifier in LTE)– Bearers in parallel– Supplementary services (CLIP/CLIR...)– Location Based Services

• Throughput measurements• Performace Testing• IODT• IOT• Drive / Field tests• Type Approval

Testing Ahead of 4G

• 4G is another order magnitude on top of the existing infrastructure

• Profitability and company viability on the line.

• Unbelievable Technology Churn

• Less ability to test manually

• Script based testing is failing

Will Your 4G be on Time?

Can you take a feature test and get it into regression before you release the product or service?

Can you run a full regression suite on a new service, new device feature, or a device software update in less than a week? In two days?

No? Better hope your competitor can’t
